High Purity Tungsten Carbide WC Powder Cas 12070-12-1, 99%

Young’s modulus, which measures 530-700 GPa (77,000-102,000 ksi), is approximately twice as stiff than steel. It is also twice as dense and nearly equal to lead or gold. Its hardness is almost the same as that of corundum, a-Al2O3. Only diamond powder and cubic boron Nitride can be used to polish and finish.

Tungsten caride can be also used in the production of

Black tungsten carbide

This hexagonal crystal has metallic luster, hardness and resemblance to diamonds. Tungsten carbide is an excellent conductor of heat and electricity. Tungsten carbide can’t be dissolve in water or hydrochloric and sulfuric acids. However, it is easily soluble and dissolves in hydrofluoric and nitric acids. Tungsten carbide in its pure form is very fragile. However, a tiny amount of cobalt, titanium and other metals can reduce the brittleness. Tungsten carbide can be used to cut steel. To increase its anti-knock capability, it is sometimes combined with titanium carbide (or tantalum) or their mix. Tungsten carbide has a chemical stability. Tungsten powder is used for cemented carbide production.

Tungsten Carbide WC Powder


produced?


Utilizing metal tungsten or carbon as raw material, tungsten powder of an average particle size between 3 and 5 mm is mixed dry with a ballmill, then press-molded and put into a graphite resist furnace. Or, you can heat it to 14001700 using an induction furnace. Preferably 15501650. W2C is produced in the hydrogen stream and reacts at high temperatures to create WC. To make WC, first tungsten Hexacarbonyl must be thermally broken down at between 650 to 1000 C in CO. Next, it will react with carbon monoxide at 1150 degC. W2C is possible at higher temperatures than these.

The chemical reaction formula

2W+C = W2C

W + C = WC

Hydrogenated tungsten trioxide (WO3) is then reduced to make tungsten dust. The average particle size for tungsten powder is 35mm. Next, press-form the mixture of tungsten and carbon black under pressure of approximately 1t/cm2. You will need to heat the block of pressurized material in a graphite pan (or crucible) at about 14001700, or more preferably 15501650 in hydrogen stream. This can be done using pure hydrogen and a low dew point (using a graphite resistance furnace) or induction electric furnace. Carburizing will give you WC. Since W2C can be generated from the beginning of the process, the reaction begins around the tungsten particle. Because the reaction temperature is very low, the unreacted and intermediate W2C will remain. The reaction must then be heated to the high temperatures mentioned above. The raw tungsten particle size should determine the temperature. A reaction can be initiated at temperatures between 1550-1650degC for large particles that have an average size of 150 mm.

The chemical reaction formula

WO3 + W+3H2 – WO3 + W2 + 3H2O

2WO3 + 3C – 2W + 3CO2

2W+C = W2C

W + C = WC

Applicaciones


Tungsten Carbide WC Powder:


Tungsten caride is used extensively in the manufacture of high-speed cutting tools and furnace structural materials. This is used in the manufacture of cutting tools, wear resistant parts, meltingcrucibles for metallics such as cobalt, copper and bismuth and wear-resistant semiconductor film.

Tungsten carbide is used for super-hard material as well as wear-resistant materials.

Tungsten carbide can be combined with many other carbides to create a strong solution. WC-TiC-Co has been used extensively to create cemented carbide tools.

Tungsten carbide can also be used to modify NbC–C and TaC–C ternary-system carbides. It can decrease the sintering temperature while maintaining excellent performance. It is also used in aerospace.

Tungsten carbide or (WC) can be made by using tungsten hydride (WO3), graphite, and an reducing atmosphere at 14001600 degrees Celsius. You can make dense ceramic products by either hot pressing or hot isostatically pressing sintering.

Tungsten caride (WC), powder, can also be used in the production of high-capacity superfine or nano-crystalline horniness alloys.

Tungsten carbide powder storage conditions:


Tungsten carbide powder dispersion and uses effects should be considered. Niobium carbide NbC Powder must be stored in vacuum bags and kept dry in a cool place. NbC powder shouldn’t be exposed to stress.

Packing and Shipping Tungsten carbide WC granules :


We offer many packing options that are dependent on the amount of niobium-carbid NbC powder.

Tungsten carbide WC powder packing:


You can vacuum pack 1kg per bag, 25kg/barrel or according to your requirements.

Tungsten carbide WC powder shipping:


Could be shipped by sea, air or express once payment has been received.
